DETAILED DESCRIPTION OF THE INVENTION

Presented herein, in part, are novel cell-free therapeutic compositions derived from human amniotic fluid (HAF). HAF is a partially characterized protective fluid contained within the amniotic sac that surrounds a fetus during pregnancy. HAF contains a complex mixture of water, salts, proteins, carbohydrates, lipids, phospholipids, urea, cytokines, growth factors, lactate, pyruvate, enzymes, hormones, taurine, amino acids, lactoferrin debris and cells. HAF also contains fine hair derived from the fetus known as lanugo, and vernix, a waxy or cheese-like white substance found coating the skin of a fetus. Vernix is produced by dedicated fetal cells and confers a protective role during fetal development and for a few hours after birth.

HAF also includes cells. The variety of cells found in HAF include cells from fetal skin, respiratory, digestive, and urinary tracts, and cells derived from the amniotic membrane, as well as macrophages, hematopoietic progenitor and stem cells. The hematopoietic progenitor and stem cells are thought to confer healing, regenerative, and developmental properties to HAF while macrophages are thought to provide some level of immune defense. Some cells isolated from HAF express neural markers, such as Nestin, β3-tubulin, GFAP, NEFH, as well as several markers of embryonic stem cells (ESCs), such as SSEA-4, Oct4, and Nanog. These cells exhibit osteogenic, adipogenic, myogenic and neural differentiation. They can also differentiate into hepatocytes and endothelial cells.

EXAMPLES Example 1—Manufacturing

Organicell Flow is an acellular therapeutic composition derived from human amniotic fluid (HAF). Organicell Flow was prepared by aseptically collecting amniotic fluid from screened and qualified donors. Once obtained, the HAF was centrifuged at 500×g for 10 minutes (min.) and 2000×g for 30 min at 4° C. to remove large cell debris. After centrifugation, the supernatant was transferred into a new vial and filtered with a 0.22 uM filter while preserving sterility.

Organicell Flow XL is also an acellular therapeutic composition derived from human amniotic fluid (HAF). Organicell Flow XL was prepared by aseptically collecting amniotic fluid from screened and qualified donors. Once obtained, the HAF was centrifuged at 500×g for 10 minutes at 4° C. The sample supernatant was then transferred to sterile conical tubes. The sample pellet was discarded. The fluid was then centrifuged at 2000×g for 30 minutes at 4° C. The sample supernatant was collected. A portion of the processed HAF (˜1/4) was set aside for later exosome resuspension. Another portion of the processed HAF (˜3/4) was used for exosome isolation. Another portion of the processed HAF was used for the “Control” sample. The filtered fluid was subjected to ultracentrifugation at 100,000×g for a minimum of 3 hours to pellet the exosome fraction. Each exosome pellet was resuspended with the processed HAF set aside for re-suspension. The resuspended exosomes were transferred into the total volume of HAF set aside for resuspension. This process was repeated until all exosome pellets were resuspended and transferred to the HAF set aside for resuspension. After resuspension was complete, the solution was subjected to filtration using a 0.22 uM filter. Filtered product was then aliquoted.

Successful production of Flow-XL was confirmed by Nanosight Nanoparticle analysis (FIG. 1 ) and exosome marker quantification by ELISA (FIG. 2 ). Using Nanosight NS300, the nanoparticle distribution of Organicell Flow (FIG. 1A) was compared to Organicell Flow-XL (FIG. 1B). The analysis demonstrated a significant increased nanoparticle concentration in Flow-XL products compared to the Flow Control (FIG. 1C). An increased concentration of exosome marker CD63 in the Flow-XL products was also demonstrated by ELISA (FIG. 2 ). The Flow-XL manufacturing process was able to elevate CD63 concentrations from undetectable levels to over 400 pg/mL.

The soluble protein compartment of Organicell Flow & Flow XL consisted of several cytokines, chemokines, growth factors and hyaluronic acid. Routine testing of the total soluble protein concentration in each Organicell Flow lot was conducted using Bradford protein analysis to ensure a reproducible protein concentration above about 1 mg/ml (FIG. 3 ). Several cytokine assays were also conducted to detect and semi-quantitatively measure the amount of cytokines and growth factors present in the Flow and Flow XL products (FIG. 4, 5A-5C & 6). The results showed that the Flow and Flow XL products contained a similar variety of pro-angiogenic, immune-modulatory¹, anti-inflammatory², pro-metabolism³, and tissue repair growth factors⁴ (FIGS. 4, 5 & 6 ). The Flow and Flow XL products also contained extracellular matrix components such as hyaluronic acid in a mean amount of about 400 ng/ml (Flow) to about 550 ng/ml (Flow XL) (FIG. 7 ).

Hyaluronic acid participates in a number of biological processes such as tissue healing, inflammation, water homeostasis, and inter-cell communication.

Nanoparticle analysis of the Flow and Flow XL products was conducted using the Nanosight NS300 (Malvern Panalytical) instrument. The results demonstrated a reproducible nanoparticle concentration in the final products with a mean concentration of 5.24×10¹¹ particles/ml and an average mode particle size of 125 nm (FIG. 8 ). The expected particle size of exosomes was 50-200 nm in diameter.

A MACsplex exosome surface marker array analysis was conducted to demonstrate that the nanoparticles observed in the Nanosight analysis were exosomes. Exosome markers CD63, CD81, and CD9 were detected in addition to surface markers associated with various subsets of exosome populations (FIG. 9 , FIG. 10 ). Results of this analysis confirmed the expression of CD63, CD81, and CD9. Interestingly, the exosomes were found to express high levels of CD133 and CD326, two markers of epithelial and epithelial progenitor cell populations^(5, 6).

The lipid-bilayer nature of exosomes allows for efficient uptake of exosome cargo into the recipient cells. Two major components of exosome cargo that are well established mediators of exosome regeneration are protein and microRNA factors. To determine the protein cargo of exosomes, a mass spectrometry analysis was conducted using the Easy nLC 1000 and Q Exactive instruments. Exosomes were precipitated from Organicell Flow using size-exclusion filtration followed by ultracentrifugation from 3 independent products (in triplicate) and subjected to protein lysis. Tune (version 2.9) and Xcalibur (version 4.1) was used to collect data while Proteome Discoverer (version 2.2) was used to analyze data. Protein expression lists were created by merging the 3 sample replicates together and commonly expressed proteins were determined using Vinny 2.0 yin diagram analysis. WebGestalt tool kit classification system was used to identify top protein function and pathway hits. The completed analysis revealed 1225 commonly detected proteins across 3 products (FIG. 11 ). The top molecular functions of identified proteins included protein-binding, ion-binding, and nucleic acid-binding with enzymes, transcription regulators, and transporter proteins representing the most abundant protein groups (FIG. 12 ). Pathway enrichment analysis revealed top hits for Integrin, PDGF, and P53 pathways. A deeper dive into the enzyme category of the protein cargo further demonstrated the presence of proteins that promote DNA repair such as DNA polymerase (beta and lambda), telomerase reverse transcriptase, and RAD50 (FIG. 13 ).

Exosomes were precipitated from 3 independent products (in triplicate) and subjected to RNA isolation for miRNA sequencing and identification (Table 1). The completed sequencing revealed 102 commonly expressed miRNAs (with a 100-copy expression minimum) (FIG. 14 ). Bioinformatics analysis was completed using the Qiagen IPA software to link 63 miRNAs to 1216 RNA targets. A top canonical pathway analysis of these mRNA targets reveals the regulation of various pathways such as hepatic fibrosis, senescence, interlukin-6 signaling, arthritis, IGF-1 and NFκ-B signaling (FIG. 15 ). Although miRNA functions vary, miRNA are powerful tools for the suppression of unwanted gene expression.

A focused analysis of mRNA targets involved in COPD pathology revealed 25 miRNA that directly target 45 genes associated with COPD through experimentally observed relationships (FIG. 17 ). Of these 45 genes, several pro-inflammatory molecules stood out as potentially therapeutic targets for Organicell Flow exosomes. As such, Hsa-mir-21 was identified to target CXCL8 (IL-8) and TNFα while Hsa-mir-191 was linked to IL-6. The upregulation of pro-inflammatory cytokines such as CXCL8, TNFα, and IL-6 were associated with the increased progression of COPD. Similarly, Hsa-mir-146a was linked to the regulation of IL-1 receptor 1, a pro-inflammatory signaling receptor mediating the inflammatory signaling of IL-1. Aside from the identification of common mediators of inflammation and tissue injury, the completed analysis also revealed a potential mechanism that targets a novel mediator of COPD. The analysis linked hsa-mir-30d expression (the 3^(rd) highest expressed miRNA in Flow nanoparticles) to the regulation of WNT5a. Increased WNT5a expression mediates impairment in mesenchymal-epithelial cross talk in COPD pathology. In a murine model of elastase-induced emphysema, it was demonstrated that inhibition of WNT-5A via IgG neutralizing antibodies induces alveolar cell function. In summary, the identification of several miRNA in Flow and Flow XL that target inflammatory and COPD associated genes has allowed us to formulate potentially therapeutic mechanisms against this disorder. Based on this data, it was hypothesized that hsa-mir-30d, hsa-mir-191, hsa-mir-21, and has mir-146a can work synergistically to suppress the expression of WNT5a, IL1-R1, IL-6, CXCL8, and TNFα to attenuate the pathogenesis of COPD.

Tests for Safety

The follow set of tests were completed on each Organicell Flow lot to ensure product safety and reproducibility:

(1) Sterility and Endotoxin Testing

Safety assessment was completed by performing endotoxin and 14-day sterility testing for the detection of bacteria, fungus, and yeast contamination. Endotoxin tests were completed in accordance to USP <85> guidelines and sterility tests were performed by VRL Eurofins, a qualified CLIA certified laboratory, in accordance to USP <71> guidelines. One vial was selected for endotoxin testing and 10% of the total lot volume was randomly selected for 14-day sterility testing at the completion of the processing procedure. The vial sample size selected for 14-day testing was determined by the USP <71> guidelines for the minimum volume and containers required based on total lot production size. Furthermore, in-process samples (2 mL total volume) were collected for 14-day sterile analysis at the beginning of amniotic fluid handling (Raw product sample) and prior to filtration (pre-filtration sample). Our release criteria for safety assessment states that endotoxin levels must be below 5 EU/ml and all samples must be negative for sterility.

(2) Bradford Analysis

Product composition testing was completed on every product to ensure lot to lot reproducibility and stability. Bradford analysis was completed on every product to demonstrate a similarity in overall protein concentration (>1 mg/ml).

(3) Nanosight Nano-Tracking Analysis (NTA)

NTA analysis was completed to demonstrate the mode particle size and concentration falls within our expected range (<200 nM mode size and >1×10¹⁰ particles per ml).

Parameter Test Method (SOP No.) Specification Sterility and Endotoxin OC-GEN-018 Sterility: Negative Testing Endotoxin: <5 EU/mL Bradford OC-TOF-008 Protein Concentration Analysis >1.0 mg/mL NTA OC-TOF-002 Particle Concentration analysis >1 × 10¹⁰/mL Particle Mode Size <200 nM

All products must meet the standard quality requirements to be deemed acceptable for clinical use. In the event a product lot fails to pass the minimum release criteria for safety and composition, a production investigation is performed by the quality assurance associated and laboratory director to determine the root cause. If positive sterility is reported, additional backup samples are sent for immediate testing. While backup results are pending, a deviation must be recorded, and batch record documents will be reviewed.

Example 2—Bronchopulmonary Dysplasia (BPD)

Studies were completed to test the safety and biological activity of the Organicell Flow-XL in a rat model of bronchopulmonary dysplasia (BPD)⁸. In this model, neonatal rat pups were placed in 85-90% oxygen for 3 days after birth to induce hyperoxic lung damage that is present in pre-mature infants diagnosed with BPD. After the 3 days in hyperoxia, Organicell Flow-XL or saline control was administered intratracheal and animals were allowed to recover for 14 days. Following the 14 day experiment, evaluation of survival and pulmonary hypertension (right ventricular systolic pressure and right ventricular hypertrophy) was completed. Survival assessment showed a 66% survival rate in saline treatment animals and a 100% survival rate in Flow-XL treated groups. Flow-XL decreased right ventricular systolic pressure compared to placebo (FIG. 16A) and provided a moderate (but not statistically significant) effect on right ventricular hypertrophy (FIG. 16B). Results of this study demonstrated a safety and biological activity of Flow-XL in an established animal model of lung disease. Successful retention of exosomes was confirmed by IVIS live imaging of infrared stained particles 2 hours after administration (FIG. 17 ).

Histological analysis of the lung tissue revealed improved alveolar structure in the hyperoxia-exposed (HYP) group who received Flow-XL treatment. Alveolarization was determined by calculating the mean linear intercept (MLI). Morphometric analysis revealed a significant reduction in the MLI in the HYP group which received Flow-XL treatment (87.4±2.5 μm) compared to HYP-PL (101±6.1 μm, p-value <0.05) (FIGS. 24A-C, M). Vascular density also decreased in the placebo (PL) treated HYP (HYP-PL) group (7.33±0.6 vessels per HPF, p-value <0.0001) compared to PL-treated room air (RA) control (RA-PL) (22.2±0.8 vessel per HPF). Vascular density in the HYP group increased with Flow-XL treatment (9.5±1.0 vessels per HPF) (FIG. 24D-F, N).

Pulmonary vascular remodeling was assessed by quantifying the percentage of muscularized vessels. Animals in the HYP-PL group had significantly increased pulmonary vascular remodeling (92.0±3.3% muscularized pulmonary vessels, p-value <0.0001) compared to RA-PL (31.33±7.1% muscularized pulmonary vessels). Flow-XL treatment significantly reduced muscularization compared to HYP-PL (65.7±6.6% muscularized pulmonary vessels, p-value<0.05) (FIGS. 24G-I, O). Immune response to the hyperoxia injury was measured by macrophage infiltration into the lung tissue via Mac-3 immunostaining. Macrophage infiltration increased in response to hyperoxia in the HYP-PL group (28.2±4.4 Mac-3 positive cells/HPF, p-value <0.001) compared to RA-PL (0±1.0 Mac-3 positive cells/HPF). HYP animals that received Flow-XL, however had significantly reduced macrophage infiltration (14.20±4.4 Mac-3 positive cells/HPF, p-value <0.05) compared to HYP-PL (FIG. 24J-L, P).

Example 3—Inflammation

Bioinformatics analysis linked 63 miRNAs to 1216 RNA targets. Major players involved in the pro-inflammatory cytokine and cytokine mediated immune response cascades found to be targeted by miRNA found in the Flow and Flow XL products include TNF, IL-6, and IL-8. Additionally, a broader array of pro-inflammatory cytokines also targeted by the collection of miRNA in the Flow and Flow XL products include FGF2, IFNB1, IGF1, IL36a, IL37, TGF-B2, VEGFA, CCL8, and CXCL12 (FIG. 18 ). Inhibition or suppression of this pro-inflammatory cytokine cascade may reduce the severity of symptoms associated elevated immune response⁹. Furthermore, miRNA in the exosome particles was found to target 148 genes associated with immune response. Together, this analysis suggests a therapeutic potential of the exosomes in immune-modulatory settings and as a potential therapy for the reduction of symptoms associated with lung inflammation (e.g., acute respiratory syndrome from COVID-19 infection).

Example 4—COVID-19 & Respiratory Distress Syndrome

One major complication of severe COVID-19 infection is the development of Acute Respiratory Distress Syndrome (ARDS). The risk of developing ARDS in a COVID-19 infection was linked to factors consistent with immune activation and a less robust immune response⁹. Extracellular vesicles derived from mesenchymal stem cells are expected to provide a significant role of protection against ARDS via the delivery of miRNA cargo such as miR-146a and miR-21-5-p found in Flow and Flow XL exosomes. Organicell Flow extracellular vesicles expressed both miR-146a and miR-21-5-p as well as 27 additionally identified miRNA that regulate 13 genes associated with ARDS disease. Representative ARDS gene targets include TNF, IL-6, FOXO3, IGFBP3, STATS, and COX-2 (FIGS. 18, 19 and 20 ). This bioinformatics analysis along with previously published results provides strong evidence that Organicell Flow may provide therapeutic relief in COVID-19 patients with ARDS and may be used as a novel treatment to reduce the overall severity of the infections. Together, this analysis suggests a therapeutic potential of Organicell extracellular vesicles in immune-modulatory settings and as a potential therapy for the reduction COVID-19 infection severity.

Example 6—Osteoarthritis

This study enrolled five subjects: adults between the ages of 21 to 80 who have symptomatic osteoarthritis of the knee and who meet all inclusion/exclusion criteria. The study duration was one year. Subjects received 1 ml of Organicell Flow via IV infusion on day 0 and were followed up on day 0, week 1, and months 1, 3, 6, 9, and 12. No adverse events were observed post 3 months of the IV infusions. All subjects were closely monitored to observe product related adverse events for first 3 months. Subjects were continued to be monitored at 6, 9 and 12 months. The following demographics, baseline characteristics of knee OA and outcomes assessedare shown in Table 2 (subjects; n=5).

No adverse events were reported up to 4 hours post IV infusion, at 24 and 48 hours post IV infusions and at 1 months post IV infusions.

Efficacy

The effect of Organicell Flow treatment on WOMAC pain scores was assessed (FIG. 21A, FIG. 22A, FIG. 23 , and Table 3A). The pain score of one patient did not have any change at day 30 as compared to day 0. For the rest of the four patients, pain score reduction ranged from 16.7%-70% at day 30 as compared to day 0. The pain score was decreased in all five patients at day 90 as compared to day 0, ranging from a 25% to 80% reduction in pain. Four out of five patients had further score reduction at day 90 as compared to day 30, ranging from 10%-40%; however, one patient had a 50% increase in the pain score on day 90 (score=12) as compared to day 30 (score=8).

The effect of Organicell Flow treatment on WOMAC stiffness scores was assessed (FIG. 21B, FIG. 22B, FIG. 23 , and Table 3B). The average stiffness scores on day 0, day 30, and day 90 were 5.4±2.2, 4.0±1.9, and 3.4±2.1, respectively. At day 30, two patients had no stiffness score changes, and the other three had a score reduction ranged from 16.7% to 60% as compared to day 0. At day 90, two patients had no score changes, and the other three had a score reduction ranged from 37.5% to 80% as compared to day 0. As compared to day 30, two patients had no score changes, one patient had 20% increase (from 5 to 6), and the other two patients both had 50% reduction.

The effect of Organicell Flow treatment on WOMAC physical function scores was assessed (FIG. 21C, FIG. 22C, FIG. 23 , and Table 3C). The physical function score is a measure of the restriction in the performance of an individual, such as difficulty getting up out of bed, getting up from a chair, walking, and climbing stairs. A high score indicates greater restriction of physical function. Accordingly, a decrease in the WOMAC physical function score indicated increased physical function. The WOMAC physical function score (mean±SD) was significantly reduced (p<0.05) on day 30 (29.8±16.2) and day 90 (24±15.5) as compared to the score at day 0 (45.4±16.9) indicating an improvement in physical function. Reduction in physical function ranged from 3.6% to 60.7% at day 30, and from 20% to 82.1% at day 90 as compared to day 0. Four out of the five patients had a further decrease in the score at day 90 as compared to day 30. The decrease ranged from 17% to 54.5%. The other patient had no change at day 30 and day 90. The effect of Organicell Flow treatment on WOMAC total score was assessed (FIG. 21D, FIG. 22D, FIG. 23 , and Table 3D). The total WOMAC score was significantly improved at day 30 and day 90 as compared to day 0 (p<0.05). The average total score on day 0 was 63±23.6, while the scores at day 30 and day 90 were 41.2±21 and 34.4±21.3, respectively. The average reduction of the total WOMAC score at day 30 and day 90 was 35.2% (ranged 10.4%-62.8%) and 49% (ranged 23.4%-81.4%), respectively, compared to day 0. As compared to day 30, four out of the five patients had further reduction in total WOMAC score at day 90, ranging from 14.5% to 50%. The other patient had a 9.3% increase in the score at day 90 (from 43 to 47).

Overall, the data herein shows that Organicell Flow is effective at reducing pain and stiffness, and improving physical function in osteoarthritis.

Example 7—COVID-19, Acute Lung Injury, Acute Brain Injury, Acute Organ Failure

The primary objective of this study was to demonstrate safety, feasibility, and accessibility of Organicell Flow for the treatment of these severely ill Covid-19 patients, and to observe post-treatment changes in clinical status improvement and inflammatory biomarker improvement that may suggest potential therapeutic efficacy. Organicell Flow was prepared as described in Example 1. The specific parameters for the Organicell Flow administered in this study were: sterility (14-day cultures: no growth for aerobic, anaerobic, and fungal contamination), endotoxin (<0.05 EU/mL), nanoparticle composition (concentration=3.26×10¹¹/mL, mode particle size=90.2 nm), protein concentration (2.83 mg/mL), and hyaluronic acid concentration (261 ng/mL).

Organicell Flow was administered to three critically ill Covid-19 patients concurrently with ongoing medical care who were monitored for 28-days post-therapy. All patients were diagnosed with COVID-19, developed respiratory failure, and were hospitalized for more than 40 days. All three patients suffered from severe, multi-organ complications induced by COVID-19 infection who were treated with Organicell Flow in addition to the authorized standard of care available at that time. These patients represent the subset of COVID-19 patients most effected by the virus. At the time of hospital admission there was no emergency authorized standard of care for COVID-19 infection. These patients were treated with supplemental oxygen, anti-inflammatories, antibiotics, antiviral medication, and other medications required to manage their multiorgan failure symptoms.

The first patient (de-identified subject CU #1) was a 74-year-old Caucasian female with multiple comorbidities including obesity, hypertension (HTN), type 2 diabetes, depression, hyperlipidemia (HLD), and vitamin D deficiency. This patient was initially admitted to the hospital 44 days prior to treatment at the study site. Initial diagnosis was acute hypoxemic respiratory failure with positive COVID-19 infection. The patient was orally intubated after 6 days in the hospital and treated for COVID-19 with pneumonia. COVID-19+ tests were reported for 20 days post-admission. Tracheostomy placement was performed prior to transfer to the study site. Patient CU #1 continued to require mechanical ventilation prior to treatment and developed acute metabolic encephalopathy with ICU delirium along with acute kidney injury and anemia. The initial COVID-19 treatment upon admission included a 10-day course of Hydroxychloroquine, three doses of Ribavarin, and Kaletra. Inclusion of additional medication was ongoing to manage complications induced by the multiple comorbidities. Ten days after transfer to the study site, Organicell Flow infusion was initiated in addition to ongoing medical treatment. Due to the patient's high BMI, it was decided to administer a total of four doses of Organicell Flow.

The second patient (de-identified subject CU #2) was a 79-year-old Caucasian female with multiple chronic comorbidities including obesity, HTN, HLD, Hodgkin's disease, hypothyroidism (HYT), and status post-left carotid endarterectomy. This patient was admitted to the hospital 47 days prior to treatment at the study site. Her initial diagnosis included septic syndrome and hypoxemic respiratory failure with positive COVID-19 infection. The initial treatment reports did not indicate if this patient received any anti-viral medication to target the COVID-19 infection; instead, the treatment included a wide range of medications to manage the severe symptoms associated with comorbidities, antibiotics (Cefepime and Vancomycin), and hemodialysis. Due to the severity of the patient upon admission, mechanical ventilation was immediately required after 2 days. The patient was extubated and then reintubated, followed by tracheostomy placement. COVID-19+ tests were reported for 16 days post-admission. Hospital course was complicated by acute kidney injury, anemia requiring blood transfusion, encephalopathy, and septic shock. The patient underwent PEG placement a few days prior to transfer to the study site. Transfer of the patient to the study site was completed for ventilator liberation and management of other comorbidities. The high BMI of CU #2 qualified this patient for four doses of Organicell Flow.

The third patient (de-identified subject CU #3) was a 66-year-old Hispanic male with comorbidities that included type 2 diabetes and HTN. This patient was admitted to the hospital 42 days prior to treatment at the study site. Initial diagnosis was hypoxemic respiratory failure secondary to COVID-19 pneumonia. Initial COVID-19 treatments included Hydroxychloroquine as an outpatient, followed by Tocilizumab on admission. Patient CU #3 required intubation that was followed by extubation and reintubation. Hospital course was complicated by hypoxemic cardiac arrest, acute kidney injury that required renal replacement therapy, acute DVT, and encephalopathy. The patient underwent tracheostomy prior to transfer to the study site. Transfer to the study site was completed for ventilator liberation, management of hemodialysis, continuation of nutritional support, and management of other comorbidities. COVID-19+ tests were reported for 8 days post-admission. Additional medication and antibiotics were incorporated throughout treatment as the patient's condition evolved. The patient received three doses of Organicell Flow beginning 9 days after transfer to the study site.

Methods

Sequential Organ Failure Assessment (SOFA) score assessment, chest X-rays, and inflammatory biomarker testing was performed to test the effect of Organicell Flow on Covid 19 patients. ChartPad Software (Technomad), a cloud-based electronic data capture platform, was used to collect patient data. SOFA score was calculated as reported in the literature (Lambden S. et al., “The SOFA score-development, utility and challenges of accurate assessment in clinical trials,” Crit Care. 23:374 (2019)) and was assessed on 0, 4, 6, 8, 14, 21, and 28 days after the initiation of Organicell Flow therapy. The SOFA score was derived from clinical and laboratory results obtained for respiration (PaO2/FiO2, mmHg), coagulation (platelets, ×103/μL), liver (bilirubin, mg/dL), cardiovascular (mean arterial pressure), neurologic (Glasgow coma score), and renal (creatinine, mg/dL).

A portable chest x-ray (CXR) was used to acquire imaging at baseline and throughout treatment to evaluate, identify, and monitor lung abnormalities. After images were acquired, analysis was performed by the radiologist at Landmark Hospital and CXR reports were generated to outline the clinical findings.

Biomarker collection occurred at 0, 4, 6, 8, 14, 21, and 28 days after initiation of Organicell Flow therapy to assess for concentration of D-Dimer, CRP, IL2, IL6, and TNFα. D-Dimer and CRP measurements were performed at the Athens Regional Labs, while IL2, IL6, and TNFα were measured by Quest Diagnostics.

Glasgow Coma Scale (GCS) scores before and after treatment of Organicell Flow for all the patients were collected. GCS is a 15-point neurological scale used in assessing a patient's level of consciousness and level of neurologic functioning. It is a widely used scoring system for quantifying level of consciousness following traumatic brain injury. The total score is the sum of the scores in three categories, each of which is scored: best motor response, best verbal response, and eye opening.

Results

The clinical status of the patients was monitored for 28 days post-initiation of Organicell Flow therapy. After treatment, the respiratory status of the patients improved and stabilized. CU #1 respiratory status improved throughout the 28 days, changing from a 21% oxygen T-collar to roomair with no oxygen therapy requirement, CU #2 respiratory status improved during the 28 days with a transition from mechanical ventilation to non-mechanical ventilation, and the respiratory status of CU #3 improved 4 days post-treatment with decannulation and subsequent removal from oxygen therapy by day 14. Furthermore, all patients were transferred out of ICU status to the step-down unit within the 28-day period (Table 4). Patient CU #1 was discharged from the hospital 29 days post-treatment initiation and patient CU #3 was discharged from the hospital 26 days post-treatment initiation. Patient CU #2 remained in the hospital as she had experienced setbacks due to aspiration but was controlled and stable in the step-down unit with ventilation and hemodialysis.

Effect on SOFA Score

Improvement in SOFA score was found in all patients. SOFA score calculations decreased from 3 to 0 in CU #1 within 28 days, from 7 to 4 in CU #2 within 28 days, and from 4 to 0 in CU #3 within 21 days (Table 5). Assessment of the individual parameters used to calculate SOFA score showed improvements in PaO2/FiO2 and Glasgow score for CU #1, improvements in Glasgow score and creatinine levels for CU #2, and improvements in PaO2/FiO2 and creatinine levels for CU #3 (Table 5). Platelet count, bilirubin, and MAP measurements remained stable throughout the treatment course.

Effect on Lung Imaging

CXR images were collected throughout the treatment and the changes from baseline to day 21 and 28 were observed and reported (FIG. 25 ). CXR analysis of patient CU #1 displayed at baseline show an infiltrate present in the left lower lobe with no defined pleural fluid. After 28 days, CXR showed basilar, infrahilar air space opacity present bilaterally in the base of the lungs. CXR analysis of patient CU #2 displayed bilateral pulmonary disease at baseline. At day 28, CXR analysis showed small pleural effusions. CXR analysis of patient CU #3 displayed bilateral upper lobe infiltrate at baseline. At day 21, CXR analysis showed residual consolidation present in the left perihilar region. There was partial interval resolution of right upper lobe pneumonic consolidation.

Inflammatory Biomarker Assessment

Quantification of inflammatory biomarkers was completed at each testing time point (Table 6). There was a slight increase in TNFα for CU #1 within 28 days. CU #1 had an elevation in CRP and IL-6 that was attributed to bacteremia from an infected vein port at day 4, 6, and 8. However, levels of CRP and IL-6 began to drop below baseline by day 14 through day 28. Additionally, D-Dimer concentration decreased in this patient on day 28. CU #2 also showed a decrease in CRP and IL-6 levels by day 14 through day 28, however, TNFα and D-Dimer remained elevated. CU #3 showed high levels of inflammatory markers TNFα, IL-6, and D-Dimer up to day 8, however, declines in all markers were reported by day 21.

Analysis of the collective data in all patients showed a reduction of SOFA score, improvement in ICU clinical status, improvement in Glasgow scores, and respiratory improvements. In addition, the patient's laboratory results have shown improvements with decreased inflammatory biomarkers.

The clinical features of patient CU #1 improved considerably with lungs improving on CXR and both mental status and kidney function returning to normal. Respiratory function of this patient improved 21 days post-treatment, transitioning from a 21% T-collar to room air PMV and decannulation on day 26, representing a considerable achievement for this patient demographic. Inflammatory marker status of this patient, IL6 and CRP, improved after the 14-day time point. The patient further improved to hospital discharge after 29 days posttreatment initiation. Glasgow scores of CU #1 improved to 15 after treatment.

The clinical features of patient CU #2 systemically improved, including respiratory function, during the treatment time course. The patient transitioned from CPAP 5 PS 10 30% ventilation to 30% T-Collar ventilation by day 28 and the acute delirium improved. This patient sustained acute kidney injury and required regular hemodialysis during the study period. Glasgow scores of CU #2 improved to 15 after treatment.

After receiving Organicell Flow, patient CU #3 displayed rapid improvement in respiratory function, with a complete decannulation from oxygen therapy by day 4. The patient had a complete recovery of renal function, had decreased creatinine concentration levels, and was removed from hemodialysis by day 17. CU #3 was discharged 26 days post-treatment initiation.

These completed case studies demonstrated human amniotic fluid-derived nanoparticles as a safe and efficacious therapeutic treatment to recover from complications induced by COVID-19 infection. The multidose administration of Organicell Flow as a therapeutic approach for patients severely ill from COVID-19 was safe and welltolerated, without the report of any serious adverse events. The molecular composition of Organicell Flow, particularly the nanoparticle population that includes perinatal secreted extracellular vesicles and exosomes, work as a therapeutic to COVID-19 patients. This study demonstrates the first use of an amniotic fluid-derived product in humans as a therapeutic to aid in the recovery from severe organ injuries induced by COVID-19 infection.

Thus, to illustrate reference to a series of ranges, for example, of 1-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-75, 75-100, 100-150, 150-200, 200-250, 250-300, 300-400, 400-500, 500-750, 750-1,000, 1,000-1,500, 1,500-2,000, 2,000-2,500, 2,500-3,000, 3,000-3,500, 3,500-4,000, 4,000-4,500, 4,500-5,000, 5,500-6,000, 6,000-7,000, 7,000-8,000, or 8,000-9,000, includes ranges of 10-50, 50-100, 100-1,000, 1,000-3,000, 2,000-4,000, etc.

Modifications can be made to the foregoing without departing from the basic aspects of the technology. Although the technology has been described in substantial detail with reference to one or more specific embodiments, those of ordinary skill in the art will recognize that changes can be made to the embodiments specifically disclosed in this application, yet these modifications and improvements are within the scope and spirit of the technology.

The invention is generally disclosed herein using affirmative language to describe the numerous embodiments and aspects. The invention also specifically includes embodiments in which particular subject matter is excluded, in full or in part, such as substances or materials, method steps and conditions, protocols, or procedures. For example, in certain embodiments or aspects of the invention, materials and/or method steps are excluded. Thus, even though the invention is generally not expressed herein in terms of what the invention does not include aspects that are not expressly excluded in the invention are nevertheless disclosed herein.

Some embodiments of the technology described herein suitably can be practiced in the absence of an element not specifically disclosed herein. Accordingly, in some embodiments the term “comprising” or “comprises” can be replaced with “consisting essentially of” or “consisting of” or grammatical variations thereof. The term “a” or “an” can refer to one of or a plurality of the elements it modifies (e.g., “a reagent” can mean one or more reagents) unless it is contextually clear either one of the elements or more than one of the elements is described. The term “about” as used herein refers to a value within 10% of the underlying parameter (i.e., plus or minus 10%), and use of the term “about” at the beginning of a string of values modifies each of the values (i.e., “about 1, 2 and 3” refers to about 1, about 2 and about 3). For example, a weight of “about 100 grams” can include weights between 90 grams and 110 grams. The term, “substantially” as used herein refers to a value modifier meaning “at least 95%”, “at least 96%”, “at least 97%”, “at least 98%”, or “at least 99%” and may include 100%. For example, a composition that is substantially free of X, may include less than 5%, less than 4%, less than 3%, less than 2%, or less than 1% of X, and/or X may be absent or undetectable in the composition.
